ADJUSTABLE ESCUTSCHEON In one embodiment, the positioning means which is also a support means is shown as a plurality of brackets and a pair of threaded rods whereby the escutcheon may be positioned relative to the ceiling at any desired point ranging through a distance of approximately 2 /5 inches of continuous adjustment from the uppermost position partially within the ceiling to the lowermost position substantially below the ceiling. The rods are externally threaded and extend upward parallel to the axes of the collars or rings. Each rod may be of steel and each rod has one of the pair of bracket members threadedly engaged thereon. Each bracket has a substantially vertically extending portion and a pair of oppositely extending substantially horizontal portions extending from the opposite ends thereof. One of the horizontally extending portions is threaded onto the threaded rod and the other horizontally extending portion is secured by screws to the inwardly extending flange of the inner ring.

BACKGROUND OF THE INVENTION As illustrative of the prior patents relating to escutcheons for sprinkler heads, there may be considered the U.S. Pat. Nos. to Metcalfe 2,946,329 and to Campbell et al. 3,195,647. The Metcalfe patent does not show any method of adjusting the escutcheon relative to the ceiling or to a recess formed in the ceiling. The Campbell et al Pat. No. 3,195,647 shows a method of adjusting the sprinkler head relative to the ceiling but does not show any escutcheon and therefore does not show any means for adjusting the escutcheon.

It is an object, therefore, of my invention to provide an improved escutcheon.

It is a further object of my invention to provide improved means of adjusting an escutcheon relative to the ceiling and relative to the position of a sprinkler head which usually extends at least partly below the ceiling but which may be positioned well below the ceiling.

It is a further object of my invention to provide an adjustable escutcheon which may be economically and practically manufactured and used.

Further objects and features of the invention will be apparent from the following specifications and claims when considered in connection with the accompanying drawings illustrating several embodiments of the invention.

In the device which I disclose herein, there are means for adjusting the escutcheon from a position in which the escutcheon is in a recessed position wholly within the recess in the ceiling or is in the standard position in which the escutcheon is partially within the recess and is partially below the recess or in an extended position in which the escutcheon is wholly below the ceiling. So far as I know, no prior art patent discloses a structure in which the escutcheon for portions of the sprinkler system may be adjusted to such a plurality of positions. It is also to be noted that the escutcheon may not only be adjusted to the three positions specified above but may be adjusted substantially infinitesimally to any point between the upper position and the lower position. That is, it may be adjusted between the recessed position and the extended position.

SUMMARY OF THE INVENTION I have found that the above and other objects can be attained by the provision of an automatic sprinkler system positioned relative to a recess in the ceiling of a building and provided for the purpose of preventing or minimizing fire damage wherein said system includes a fluid supply pipe, a sprinkler head attached to the pipe, and a valve associated with the pipe and the sprinkler head arranged to open if a fire occurs in the vicinity of the sprinkler head,

wherein there is provided in combination an escutcheon for protecting and beautifying the installation and means for adjusting the position of the escutcheon from a position wholly within the recess to a portion wholly below the recess and also to various positions relative to the sprinkler head.

The objects can also be attained by the provision of such an automatic sprinkler system wherein there is provided in combination an escutcheon for protecting and beautifying the installation and a universal support fixture adapted to position said escutcheon in any one of a plurality of positions relative to said ceiling and said recess and relative to the parts of the sprinkler system wherein said escutcheon is formed by a plurality of tubular collars one of which forms an outer housing and another of which forms an inner housing having a diameter slightly smaller than the diameter of the outer housing, is telescoped or positioned within the outer housing, the inner housing has an inwardly extending substantially horizontal flange contacting with a portion of the sprinkler head and positioning ane supporting the escutcheon; and

wherein there is also provided means for adjusting the two collars relative to each other to any position intermediate an extreme recessed position and an extreme extended position.

DETAILED DESCRIPTION FIG. 1 is a view in elevation showing a ceiling 10 having a sprinkler head 11 of an automatic sprinkler system for minimizing fire damage. As shown in FIG. 2, there is an escutcheon 12 surrounding a substantial portion of the sprinkler head, which sprinkler head includes a valve 13 controlled by levers 14 and 15 which are normally held in a position to keep the valve closed by a meltable link 16. The sprinkler head includes an upper portion 17 and a lower portion 18. The escutcheon 12 is positioned and supported by the upper portion 17 of the sprinkler head and, as stated, surrounds a part of the-lower portion 18 of the sprinkler head of a head inches standard sprinkler.- The escutcheon 12 consists of an outer housing 21 formed as a tubular collar and having an outwardly horizontally extending flange 22 and a two-part inner housing 23. When the two parts of the housing 23 are held together they form a tubular collar having an inwardly extending flange. The two parts of the housing 23 are designated 24 and 25. The flanges of the housing 23 are respectively designated 26 and 27. The upper portion of the sprinkler head 17 is formed with a groove 19 (see'FIGS. 12, 13, and 14) in which the inner flanges 26 and 27 rest to support the supporting structure for the escutcheon 12 and the escutcheon 12 itself.

There are provided a pair of mounting brackets 28 and 29 which are in a sense Z-shaped in form and consist of flat straps having their opposite ends bent in opposite directions at a angle. Associated with these brackets 28 and 29 are a pair of threaded steel rods 31 and 32 which are at their upper ends secured to and threaded within holes in the outwardly extending portion of the brackets or straps 28 and 29. The lower end of the rods 31 and 32 are secured by acorn lock nuts 41 and 42 to the flange 23 at opposite sides of the escutcheon. The lower ends of the brackets 28 and 29 are secured to the inwardly extending flange portion of 26-27 of the inner housing 22 by four machine screws 43, 44, 45 and 46. Water or other liquid for'controlling fire is supplied to the sprinkler head by means of a relatively large (probably 1 inch) steel supply pipe 51 and a reducer (usually 1 inch to one half inch) coupling 52.

In FIG. 10 there is shown a topplan view of the escutcheon structure and in FIG. 11 there is shown a bottom plan view thereof. Itmay be seen that the inner housing 23 is formed or two halves 24 and 25. The lower flange of mounting brackets 28 and 29 are secured to flange 24 by machine screws 43 44, 45 and 46, and the upper flange of mounting brackets 28 and 29 are formed with threaded openings by which the brackets ar adjustably secured to threaded steel rods 31 and 32. Threaded onto the lower ends ofthreaded rods 31 and 32 are acorn lock nuts '41 and 42 whereby the rods 31 and 32 are secured to the outwardly extending I flange 22 of outer housing 21.

Referring now to FIGS. 12-20 inclusive, wherein I have shown another embodiment of my invention, and especially to FIGS. 12-14, it will be seen that l have shown associated with a ceiling an escutcheon 112 having a sprinkler head 111 and an escutcheon 112, of which the outer collar or housing 121 has a flange 122 and the inner collarorhousing 123 has inwardly extending flanges 126 and 127.

Referring also to FIGS. 15-17 inclusive, it may be seen that the inner housing 123 is formed in two halves 124 and 125. It has a composite inner flange 126-127. Teeth 128 are formed on the outer surface of each of these halves and a lock is provided as'at 129 so that the two halves may be locked together when desired.

Now referring especially to FIGS. 19 and 20, it may be seen that the outer collar or housing 121 is formed turning the two collars relative to each other for a few degrees, the teeth will be out of alignment. Then the two collars may be adjusted vertically relative to each other and then turned backso that the teeth are in alignment so that the two collars are adjusted relative to. each other.

A fourth arrangement of the tubular collars or housings 21 and 23 is not illustrated but may be used if desired. Therein the tubular portion of both of the housings 21 and 23 extend downwardly. However such arrangement need not be used because such arrangement will achieve only positions of adjustment such as are illustrated in FIGS. 5, 6 and 8.

OPERATION The embodiment shown in FIGS. 1 to inclusive is assembled by placing the inner collar 23 around the neck of the portion 18 of sprinkler head 11, placing the outer collar 21 around the inner collar 23 as desired as shown in either of FIGS. 3, 5, or 7, securing the brackets 28 and 29 to the flanges 26 and 27 of the inner housing 23, passing the rods 31 and 32 upward through the flange 22 of the outer housing 21 and then through the threaded openings in brackets 28 and 29, turning the rods 31 and 32 to secure the desired adjustments and securing the acorn nuts 41 and 42 on the lower ends of the rods 31 and 32 to bear against the ceiling 10.

The embodiment shown in FIGS. 11-20 is similarly assembled and adjusted.

It is to be understood that while detailed drawings and specific embodiments are given, they are for the purpose of illustration only, that the apparatus of the invention is not limited to the precise details and conditions disclosed, that the method of the invention is not limited to the precise steps disclosed, and that various changes may be made therein without departing from the spirit of the invention which is defined by the following claims.
